Abstract
Selon l'invention, un appareil de masque destiné à être utilisé dans un système d'assistance respiratoire peut comprendre une articulation sphérique au moins partiellement définie par un boîtier, un élément sphérique, ainsi qu'un élément de montage. Le boîtier peut être conçu pour supporter un coussinet conçu pour constituer un joint d'étanchéité contre le visage d'un patient. Le boîtier peut comprendre un premier côté définissant une première ouverture de boîtier et un second côté conçu pour faire face au coussinet et définissant une seconde ouverture de boîtier. L'élément sphérique peut être positionné dans la première ouverture de boîtier et peut définir une ouverture d'élément sphérique conçue pour le passage de gaz à travers la première ouverture de boîtier. Le système de montage peut être conçu pour fixer l'élément sphérique dans la première ouverture de boîtier de sorte que le boîtier, l'élément sphérique et le système de montage définissent une articulation sphérique permettant à l'élément sphérique de tourner autour de multiples axes relativement au boîtier et au système de montage.
